Natriuretic peptide signalling: molecular and cellular pathways to growth regulation.

Natriuretic peptide system in the rat submaxillary gland

The heart atria represent the major site of synthesis for atrial natriuretic peptide (ANP) which exerts potent natriuretic, diuretic and vasoactive functions. Recently, ANP-immunoreactivity has been detected in extracardial organs involved in water and electrolyte homeostasis, such as the intestine and certain exocrine glands. The present study investigates ANP in the parotid gland. It was found by immunohistochemical techniques that the peptide is localized in ductal cells of the gland. An analysis of the immunoreactive material by high-pressure liquid chromatography and radioimmunoassay revealed the prohormone of ANP (ANP 1-126) and the biologically active fragment (ANP 99-126). Furthermore, Northern blot hybridization disclosed the presence of mRNA coding for ANP. It is suggested that ANP is synthesized and released from the parotid gland and functions in the control of saliva production.

Regulation of inositol phosphates, calcium and protein kinase C in the lacrimal gland

Atrial natriuretic factor (ANF) is a cardiac hormone with various functions in body homeostasis. It is also processed in the brain and in the peripheral nervous system where it appears to play a role as a neuromodulator. Little is known about the presence of ANF throughout the spinal cord of the guinea-pig. We therefore examined the distribution of ANF and its possible interrelation with primary sensory afferents in this species. Using enzyme- and fluorescence-immunohistochemistry on deparaffinized sections, ANF-like immunoreactivity was found to be present in nerve fibers in laminae I/II of the spinal cord and in neurons of spinal and trigeminal ganglia. Tachykinins and ANF coexisted in very few fibers of the spinal cord but did not coexist in primary sensory spinal or trigeminal neurons. Our results indicate that spinal ANF-immunoreactive fibers are of dual origin, primary sensory and non-primary sensory. The possibly heterogeneous source of the non-primary sensory ANF, its possible coexistence with other co-transmitters and functional implications are discussed.
